INA186A3IDDFT

Texas Instruments · Current Sense Amplifiers · TSOT-23-8

INA186A3IDDFT from Texas Instruments, in a TSOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VS power_in Power supply input, 1.7 V to 5.5 V.
2 ENABLE input Digital enable pin; device enabled when driven to VS and disabled when driven to GND with output placed in high-impedance state; must be externally driven or connected to VS if not used.
3 REF input Analog reference input enabling bidirectional current detection through externally applied voltage ranging from GND to VS.
4 GND power_in Analog ground reference.
5 OUT output Analog output providing the gained voltage difference from IN+ to IN- pins offset by voltage applied to REF pin.
6 NC unconnected No internal connection; may be left floating, grounded, or connected to power supply.
7 IN+ input Current sensing amplifier positive input; connect to bus voltage side of sense resistor for high-side sensing or load side for low-side sensing.
8 IN- input Current sensing amplifier negative input; connect to load side of sense resistor for high-side sensing or ground side for low-side sensing.
